Dec 19, 2023 (Nanowerk News) A low-cost technology involving nanoparticles loaded with antibiotics and other antimicrobial compounds that can be used in multiple attacks on infections by the bacterium responsible for most cases of tuberculosis has been developed by researchers at São Paulo State University (UNESP) in Brazil and is...

Dec 19, 2023 (Nanowerk Spotlight) Genetically engineered microbes hold astonishing potential as living factories, diagnostic tools, environmental cleansers, and beyond. Yet for all their promise, these organisms remain largely confined to carefully controlled laboratory settings, unable to thrive amid the variable conditions of natural and industrial habitats. The fragility of...

Dec 19, 2023 (Nanowerk News) A group of researchers has created a simple and inexpensive means to visualize the atomic state of hydrogen. Details of their breakthrough were published in the journal Acta Materialia ("In situ visualization of misorientation-dependent hydrogen diffusion at grain boundaries of pure polycrystalline Ni using a...

Dec 18, 2023 (Nanowerk News) Rice University materials scientists developed a fast, low-cost, scalable method to make covalent organic frameworks (COFs), a class of crystalline polymers whose tunable molecular structure, large surface area and porosity could be useful in energy applications, semiconductor devices, sensors, filtration systems and drug delivery. “What...

Dec 18, 2023 (Nanowerk News) A study conducted by pre-PhD researcher Pablo S. Valera and recently published in PNAS ("SERS analysis of cancer cell-secreted purines reveals a unique paracrine crosstalk in MTAP-deficient tumors") demonstrates the potential of surface-enhanced Raman spectroscopy (SERS) to explore metabolites secreted by cancer cells in cancer...
